Easy Way to Remove Blackberries, No Chemicals

Thought I'd share the way I remove blackberry brambles without use of chemicals or pulling out.

Here is a link that might be useful: Photos & Steps to Removing Blackberries w/o Chemicals

The linked webpage depicts a large-scale method of bramble control requiring heavy machinery.

The principal is good though. It's given me food for thought, except that most of our bberries are in places that aren't flat enough to run machinery.

The method above works, for the most part, on rather level ground. Operating a brush hog is not for the timid or elderly.

My ten acres is rather hilly. I take a pole pruner and reach in to the crowns and cut them off and then pull the vines out. A gaff hook works for the crowns. What's left is easily pulled.
A common misconception is that Blackberries spread underground and then sprout. They do not. They spread like strawberries. I try not to let any vine tips root during the fall and winter on areas yet to be conquered.

I will debate the fact that they don't spread underground. The easiest way for them to spread is overground. But, my neighbor has unruly blackberry bushes and I get them sprouting in my yard up to 20 ft from the fence line. I yank them up and they lead towards her yard although the root usually breaks before I get to the fence line unless it's a close one.

When I lived in Seattle I had some Himalayan blackberries trained on a fence. They never spread underground in six years. Maybe they do, but it hasn't been my experience.

The root leads back to her house, or a section of branch does? Rooting of branch tips is common, as is branches growing flat on the ground and getting buried.

I would say that wild blackberries certainly can spread underground, but this is not their natural habit. I have dug up blackberry clumps and invariably many sprouts will pop up from the roots left behind, despite my best efforts to get all the roots.
A 20' long root that was severed from the mother plant would most certainly sprout canes. Even if not severed, I would think under some conditions they would sucker up.

The root leads back to her house. I'm religious about keeping her invasive plants on her side of the fence but can't do much about the underground raspberries until they show up. The 20 footer was an anomaly, most are in the 10 ft range.

Raspberries are a whole 'nother ballgame.

While I did this method for a large area, I also modified the idea for a smaller would-be gardening area about 25 X 50 feet.

1. First I pruned accessible large canes to the ground,
2. Then I weed-whacked the thinner canes.
3. Moved forward and repeated.
4. I removed the debris large enough to impact mowing.
5. And mowed to mulch the loose canes
6. Planted grass, watered, and mowed regularly to control brambles until grass took over.

I've heard that if you mowed them down at 2 weeks interval, they eventually have no energy left to keep growing.
But you must be diligent and keep mowing them for an entire season.
Good Luck

I've been mowing my blackberries in a grassy field diligently for almost four years. They have some massive roots. They haven't given up yet, but neither have I.

I don,t post here very often but this has been such a big problem for me I had to chime in. The bigger leafed ones can be killed by cutting down the canes the smaller leafed ones spread under ground. I have been mowing my field for years and the small ones just won,t give up . The bigger ones were killed the first year here. I read a article somewhere a few years ago about the different types of blackberrys and the roots can spread and come up as far away as 80 feet with the right kind of berry. I just don,t remember thier names. But it does seem to be my exp. with the smaller leafed ones.
